The correct answer is carbon film.  

A carbon film or the carbonaceous film refers to a species outline of a fossil. It is a kind of fossil found in any rock when an organic substance is compressed, leaving behind the carbon film or residue.  

When a species is buried beneath the various layers of sediment, the heat and pressure pile up. These circumstances make the liquids and gases to expel from the body, leaving behind a thin film of carbon residue, producing an outline of the original species known as a carbon film.

Can someone explain to me in depth the difference between covalence and ionic bonds
Ulleksa [173]
In covalence bonding, the two atoms forming the bond share the electrons between themselves, which is what creates the bond.

In ionic bonding, one atom sees that the other is lacking an electron so, given that it has an electron that it can afford to lose, it gives it to the other atom.

What are animals whose body temperature is regulated mainly by internal bodily processes called?
sweet [91]

Endotherms are animals whose body temperature is regulated mainly by internal bodily processes. Endotherms are warm blooded animals such as birds and mammals that maintain a constant body temperature independent of the environment. Endotherms require high quantities of fuel to produce heat for their survival under low external temperatures.

koban [17]

Answer:

The cutaneous membrane is made of a simple columnar epithelium

Explanation:

Cutaneous membrane is the membrane of the skin. This membrane protects the skin from the physical and chemical damage.

Cutaneous membrane is present on skin and exposed to the external environment. This membrane is made of stratified squamous epithelium and keratinized and consist of the underlying layer of dermis. Hence, the membrane is not made upof simple columnar epithelium tissue.

Thus, the correct answer is option (3).

How does the structure of a brain cell related to its function?
lesya [120]

Solution:

Structure dictates function. Ribosomes provide another good example of structure determining function. These small cellular components are made of protein and ribosomal RNA (RNA).Their main function is to translate messenger RNA, or mRNA, into strings of amino acids called proteins.

The structure and shape of each type of human cell depends on what function it will perform in the body. For example, red blood cells (RBCs) are very small, flat discs, which allows them to easily fit through narrow capillaries and around sharp corners in the circulatory system to deliver oxygen throughout the body.

Neurons carry messages from the brain and spinal cord to the rest of the body, using electrical signals down their lengths and chemical signals between neurons. Since electrical signals travel much faster than chemical signals, neurons are long and thin to minimize the number of slower chemical signals that would be required between links in a chain of many shorter neurons.

The elongated shape of muscle cells allows the contraction proteins to line up in an overlapping pattern that makes muscle flexing possible.

And human sperm cells’ structures allow them to “swim” long distances to reach an egg for fertilization. They do this by using flagella, their long whip-like tails, and also by being very small, carrying little more than the DNA for a potential zygote.

This is the required answer.

How can roots, stems, and leaves all be involved in food storage?
shepuryov [24]

Answer:

Plant produces food material in the process of photosynthesis in the leaves. The food that is produced in the form of glucose (sugar) is transported from the leaves to other parts of the plants such as roots, stem and seeds with the help of water. When the glucose reaches to the storage part it is stored in the form of starch.

For example, in carrot and potato food is stored in roots while in sugar cane the food is stored in the stem.
